Lenovo Flex System Enterprise Chassis with 2 x 2500W AC PSU, Rackable

Popis produktu:

Flex System is the next generation of blade technology with more performance and bandwidth and far more capability to consolidate and virtualize than previous systems. Flex System is anchored by the Flex System Enterprise Chassis which enables high-speed performance with integrated servers and networking. Furthermore, its flexible design can meet the needs of varying workloads with independently scalable IT resource pools for higher utilization and lower cost per workload.

Firmware                                                                          Chassis with first generation Chassis Management Module (68Y7030): IBM-signed firmware
                                                                                       Chassis with Chassis Management Module 2 (00FJ669): Lenovo-signed firmware
Form factor                                                                      10U rack-mounted unit.
Maximum number of compute nodes                               14 half-wide (single bay), seven full-wide (two bays), three double-height full-wide (four bays) or one quadruple-height full-wide (8 bays). Mixing is supported.
Chassis per 42U rack                                                      Four.
Nodes per 42U rack                                                        56 half-wide, or 28 full-wide.
Management Chassis                                                      Management Modules 2 (CMM2) modules provide chassis management. One or two CMM2s standard, depending on the model and the use of two provides redundancy. Earlier models of the Enterprise Chassis use the first generation CMM. The CMM2 interfaces with the integrated management module (IMM2) integrated in each                                                                                         compute node in the chassis. Optional Lenovo XClarity Administrator for hardware resource management with integrators to VMware vCenter and Microsoft System Center, including virtualization, networking, and storage management. Chassis with first generation CMM can be upgraded to CMM2 however CMM and CMM2 cannot be                                                                                         mixed.
I/O architecture                                                               Up to eight lanes of I/O to an I/O adapter card, with each lane capable of up to 16 Gbps bandwidth. Up to 16 lanes of I/O to a half-wide node with two adapters. A wide variety of networking solutions, including Ethernet, Fibre Channel, Fibre Channel over Ethernet (FCoE), and InfiniBand.
Power supplies                                                                Up to six power supplies that can provide N+N or N+1 redundant power. AC power supplies are 80 PLUS Platinum certified and provide over 94% efficiency at 50% load and 20% load. Each power supply contains two independently powered 40 mm cooling fan modules.
